Brightness
  • Decrease the value to make the printed image darker and increase it to make the printed image brighter.
  • If you increase the value too much, overexposure of bright areas may occur.
  • If you decrease the value too much, underexposure of dark areas may occur
  • Can be specified using the RPCS/PCL/PS drivers.

Contrast
  • Increasing the contrast makes bright areas brighter and dark areas darker.
  • Decreasing the contrast makes bright areas darker and dark areas brighter.
     
  • To make the printed image sharper, increase the value.  
  • To prevent white halation in bright parts and black crush in dark parts, decrease the value. 
  • If you increase the value too much, overexposure of bright areas and underexposure of dark areas may occur.
  • If you decrease the value too much, the printed image may become unclear.
  • Can be specified using the RPCS/PCL/PS drivers.

Saturation
  • Increasing the saturation makes the printed image more vivid.
  • Decreasing the saturation makes the printed image blander.
  • If you increase the value too much, it may lower the color gradient, resulting in a difficulty to distinguish colors.
  • The printer’s color gamut is limited, so even if you increase the value, it may not make any difference.
  • Can be specified using the RPCS/PCL driver only.

RGB Adjustment (Adjust Each Color)

When using the RPCS/PCL driver, adjust the tone (color gamut) by this method.

  • Increasing "Red" makes "M" and "Y" more vivid and "C" less so.
  • Decreasing "Red" makes "M" and "Y" less vivid and "C" more so.
  • Increasing "Green" makes "C" and "Y" more vivid and "M" less so.
  • Decreasing "Green" makes "C" and "Y" less vivid and "M" more so.
  • Increasing "Blue" makes "C" and "M" more vivid and "Y" less so.
  • Decreasing "Blue" makes "C" and "M" less vivid and "Y" more so.

CMYK Adjustment (Adjust Each Color)

When using the PS driver, adjust the tone (color gamut) by this method.

  • Increasing and decreasing the value in "Black" corresponds with "K".
  • Increasing and decreasing the value in "Cyan" corresponds with "C".
  • Increasing and decreasing the value in "Magenta" corresponds with "M".
  • Increasing and decreasing the value in "Yellow" corresponds with "Y".
